The ABCB10 gene helps mitochondria, the energy making parts of cells, support heme production, which is a key step in making hemoglobin for red blood cells. If it does not work properly, cells may have more trouble handling oxidative stress and making healthy red blood cells, which can contribute to anemia and lower oxygen delivery. The protein made by this gene helps your cells move materials across the inner membrane of mitochondria.
What is a gene?
Genes are stretches of DNA that carry instructions your cells use to make molecules or regulate processes in the body. Some genes provide the directions for producing proteins, the functional parts of cells. Other genes mainly help determine when certain processes happen, where they happen, and how strongly they occur. Taken together, genes affect how the body develops and works, and they can influence how you respond to food, stress, or medications. More on this topic is available in the LearnHub.
Overview
ABCB10Gene function
What if the gene works
The ABCB10 gene helps mitochondria, the cell’s energy centers, support red blood cell development. Its protein also helps protect cells from oxidative stress, a type of chemical strain that can build up during normal cell activity.
Risk
What if the gene does not work
Milder to more severe variants in the ABCB10 gene can reduce how well its mitochondrial transport protein works. This may weaken heme production support and the cell’s handling of oxidative stress, especially in developing red blood cells.
Treatment
What does that mean for your treatment
No ABCB10-specific treatment or management approach is currently established for people with a pathogenic variant in the ABCB10 gene. The ABCB10 gene is being studied as a possible drug target and biomarker in cancer and other conditions linked to mitochondrial stress, but this has not led to treatment choices in clinical guidelines.
Gene function
What if the gene works
Inside your cells, mitochondria need a steady flow of materials to keep energy use and blood building on track. The ABCB10 gene helps manage that flow across the inner membrane of mitochondria. Its activity is especially important when cells are making heme, the iron containing part of hemoglobin.
The ABCB10 gene helps move selected molecules across the inner membrane of mitochondria, using cellular energy. This steady traffic supports normal work inside these energy making parts of the cell.
Its transport role helps supply steps needed to build heme, the iron containing part of hemoglobin. This is part of how the ABCB10 gene helps make hemoglobin as red blood cells develop.
Inside mitochondria, ABCB10 activity helps cells handle oxygen related stress during routine metabolism. By keeping mitochondrial processes more stable, it supports steady day to day cell function.
What is a variant?
A genetic variant is a small difference in the DNA sequence within a gene. These changes are common and are part of normal human diversity, including differences in appearance, metabolism, and how the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. In some cases, though, a variant can change the function of a gene more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
ABCB10 gene variants can change the protein’s shape, stability, or ability to use ATP (the cell’s energy source), which may reduce how well the protein is made or placed in mitochondria, the cell’s energy centers. In understanding how ABCB10 gene variants affect protein function, milder variants may partly lower activity, while more severe variants that disrupt the genetic instructions can greatly reduce or eliminate the protein. These effects vary by the exact DNA change.
How variants are linked to conditions
Current evidence has not yet established how the ABCB10 gene variants are linked to conditions in a broadly confirmed way. If you have a reported variant in the ABCB10 gene, your doctor or genetic counselor can explain what that specific result may mean for you and your family.
A variant is not necessarily a diagnosis
Variants in genes are a normal feature of human biology and are widely found in the general population. Most have no direct effect on health and simply contribute to natural human diversity. For many genes, carrying a variant associated with a condition indicates a possible link rather than a confirmed diagnosis, especially when multiple genes and environmental factors play a role. In some situations, though, a single well-characterized variant in a specific gene can be enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There isn't yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the ABCB10 gene. If a change in ABCB10 is found on genetic testing, a doctor or genetic counselor can help explain what it may mean in the context of your personal and family health history.
Inheritance of ABCB10 variants
There is not yet a broadly confirmed Mendelian inheritance pattern tied to a specific ABCB10-related condition, so the answer to how ABCB10 gene variants are inherited remains cautious and may evolve as research develops. The ABCB10 gene is located on chromosome 1, which is an autosome, so you inherit one copy from each parent. In practical terms, any ABCB10 variant a person carries would come through the usual inheritance of autosomal genes, rather than through a sex chromosome pattern.
What does my ABCB10 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the ABCB10 gene, and this picture can change as research grows. If you have a specific ABCB10 result and want to understand what it could mean for your relatives, a doctor or genetic counselor can help explain it in the context of your personal and family history.
Genetic information
Genetic testing
How you find out about variants
Testing for variants in the ABCB10 gene usually uses a blood sample, cheek swab, or saliva sample. The lab reads your DNA and compares the ABCB10 gene with a usual reference sequence. It is often included in a test that checks several genes at once, with results reported as likely benign, uncertain, or linked to disease.
When should I consider getting a genetic test?
There is not yet a broadly established, ABCB10-specific reason for genetic testing in routine care. Whether testing makes sense depends more on your personal health and family history, and this is best discussed with a doctor or genetic counselor.
A genetic result is only one part of your health story
A genetic result can provide useful insight, but how much it reveals varies by the condition and the specific type of variant. Many factors, including lifestyle, environment, age, and medical history, influence how the body functions over time. For some conditions, especially those affected by many genes, genetic information provides context rather than certainty and is best interpreted together with other parts of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, genetic results can also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. One person may break down a drug more slowly, while another may process it faster or be more sensitive to its effects. This is common and can influence how well a treatment works or the chance of side effects.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in genes can affect the way medications work. It studies the relationship between genes and drugs to better understand why the same treatment may work differently from one person to another. For many medicines, genes can influence how strongly a drug works or how the body processes it. This information can help support more informed, individualized treatment decisions.

Drugs influenced by the ABCB10 gene
When should I seek medical advice?
There is not yet a broadly confirmed role for this gene in guiding medicine choices, so any concerns about side effects, treatment response, or your overall health are best discussed with your doctor.
